Effect of Boron on properties of nm450 plate impact resistance

The company adheres to green development, supported by scientific and technological innovation and technological progress, vigorously advocates the NM450 plate impact resistance production and life style of saving, environmental protection, civilization and low carbon, adheres to the new industrialization road and the sustainable development road. Actively carry out international trade and maintain stable economic and trade relations with more than 80 countries and regions including the United States, Germany, France, the United Kingdom, Japan, South Korea and Australia.

Steel Q345R (HIC) is a Q345R pressure vessel plate with hydrogen induced cracking resistance test. Q345R(R-HIC) plate is based on Q345R (HIC) and SSCC test, namely sulfide stress corrosion test. The delivery status of Q345R (HIC) and Q345R Q345R(R-HIC) plate is normalizing, - 30 ℃ impact, level I flaw detection, process reference standard GB713-2014. NM450 plate impact resistance, Q345R (HIC) and Q345R (R-HIC) plates are smelted by electric furnace + refining outside the furnace. The smelting process is Ca-treated, and should be intrinsically fine-grained steel. The actual grain size is 5 or above.

Alloy steel plate is a kind of high strength steel plate, which has good wear resistance. It is suitable for road laying, factory floor and other fields with high wear resistance requirements. The performance of the NM450 plate impact resistance, alloy steel plate is more prominent. The alloy steel plate has good high temperature resistance and low temperature resistance, which will not cause material deformation in any high temperature and low temperature environment. The strength retention of alloy steel plate is better, and the material stability is better.

Diffusion annealing of NM450 plate impact resistance, wear-resistant plate is to reduce the non-uniformity of chemical composition and structure of metal ingot, casting or forging billet, heating it to high temperature and holding for a long time to make the elements in the steel plate fully diffuse. Due to the long heating cycle and high temperature of diffusion annealing, although the composition of the steel is uniform, the structure of the steel plate is seriously overheated, and the grains grow violently, and the toughness and plasticity are poor. Diffusion annealing is widely used in ingots, casting and forging billets with high quality requirements due to its high energy consumption and serious burning loss.

ASTM A285 grade A standard specification for pressure vessel plates. NM450 plate impact resistance, carbon steel, low- and intermediate-tensile strength. ASTM A285 grade A plates are normally supplied in the as-rolled condition. The plates may be ordered normalized or stress relieved, or both.Supplementary Technology: HIC Test I NACE MR0175 1 215 | Z25 | 235 | S57 | S57.1| S58 | S58.1 1S3 |S4 Thickness: 6MM to 300MM.Width: 1500mm to 4050mm.
